A viable quantum internet a network in which information stored in qubits is shared over long distances through entanglement would transform the fields of data storage, precision sensing and computing, ushering in a new era of communication.
This month, scientists at Fermilab, a U.S. Department of Energy Office of Science national laboratory, and their partners took a significant step in the direction of realizing a quantum internet.
In a paper published in PRX Quantum, the team presents for the first time a demonstration of a sustained, long-distance (44 kilometers of fiber) teleportation of qubits of photons (quanta of light) with fidelity greater than 90%. The qubits were teleported over a fiber-optic network using state-of-the-art single-photon detectors and off-the-shelf equipment.

Precision sensing, data storage, and computing could be completely revolutionized by a viable quantum internet a network where information stored in qubits is shared over long distances via entanglement leading to a new communication era.
